The cinders which are deposited in the cinder hopper, 6, are dischargedtherefrom by the suction 'nduced. by the exhaust blast, by which theyare drawn into and throu h a 10 cinder cooling conduit and ejectedtherefrom throughthe exhaust nozzle, 64;. In lieu of using, as a cinderconduit, a pipe of considerable length, extending first rearwardly fromthe cinder hopper and thereafter forwardly to the exhaust pipe andnozzle, as in the application Ser. N o. 47 1,262 aforesaid, I providesaid conduit in the form of a plurality of return bend, or alternatelyreversely extending, passages or channels, 11, which 2 communicate atalternately opposite ends, so

as to form a continuous conduit. Said passages are preferably ofrectangular section, and are formed in a radiator casing, 11, which issecured detachably to the cinder hopper, 6, over anopening in thevertical front wall thereof. The radiator casing, 11., is a box or chestof cast or'wrought metal, of substantially rectangular transversesection, and having openings in its ends, the

rear opening registering with a corresponding opening in the front ofthe cinder hopper, and the front opening being closed by .a removablecap -or cover, 11. The bottom of the radiator casing is located a shortdislance above that of the cinder hopper, and a deflecting plate, 11.,projects downwardly and rearwardly from the top of the lowest of thechannels, ll", so as to cause the current of cinders to be drawn belowsaid chanuel and reversed in direction before entering it.

The plates or partitions. between the alternately forwardly andrearwardly extending channels, 11 are, for convenience and simplicity ofillustration, indicated in Figs. 1 and 2 as beipg formed integral withthe body of the casing, but they may, as shown in Fig. 3, be madeseparate therefrom, either individually or in one or more sets orsections, so as to be renewable when sufliciently worn by the abradingaction of the cinders to render renewal necessary or advisable. To moreef ectually resist this abrading action, the plates or partitions, aswell as the body of the radiator casing, may, with advantage, he made ofspecial material possessing a high degree of hardness, as, for example,chilled cast iron or manganese steel.

Among the advantages of the formation of the cinder cooling conduit in aregister casing, as above described, may be enumerated economy andcompactness in the con struction of the ap iiaratusg the avoidance of anadditional passage in a cylinder saddle or saddles; facility of renewalof worn or cinders from the hopper,

In and by their traverse through the channels of theradiator casing, the. aggregate length of which is considerable, andtheir admixture with the exhaust steam, the cinders will bedisintegrated, reduced in tein-' perature, and extinguished when theyare discharged from the stack, and, consequently, risk of fire damage toproperty adjoining always obtained to a substantial extent will beeliminated.
